Load sharing rates of an internal combustion engine and an electric motor of a hybrid powered vehicle are definitely controlled to improve fuel efficiency of the vehicle during an auxiliary running with using power of the electric motor together with power of the internal combustion engine when a pressing amount of an accelerator pedal of the vehicle is small. In response to a pressing amount information of the accelerator pedal inputted to a hybrid control circuit, the hybrid control circuit calculates the load sharing rates of the internal combustion engine and the electric motor by referring to a preliminarily set control map and controls the motor according to its load sharing rate. The hybrid control circuit sends an electric signal corresponding to the load sharing rate of the internal combustion engine to the internal combustion engine control circuit, instead of the pressing amount information of the accelerator pedal.
